How to kill:

Find some in the shallows

Lure towards shore or at least to where you can stand Shoot with bow

Boom! Bio toxin

Just use a crossbow? Thats easy with that even more with a rare one out of an drop

These things are in the herbivore category, if so, then why are they aggressive? Is it the same thing with the therinzosaurus.

Go fire on fire and shock with these guys with electrophorus

Will take you off shadowmaes!!!!

If you kill them in one hit the other jelly’s won’t shock you.

The most annoying and dangerous creature in the ocean, you can counter it only with the Tuso

Wolf are not affected my them so they are great.

Megalodon lasted 10 minutes since I got it because of this, just run

When you see some you must curls them into the near of your raft.They wont attack you on the raft and you can easily shot them from it.

Best way to kill-get arrows stone or metal your choice

Leave all resources at base go to water 💧 shoot and run back to land then shoot 🔫 till death you can harvest bio toxin from their bodies

When im in mobile ark i go near this creature and this creature following me near the beach but 1 or 2 cnidaria die because get push by another cnidaria and i know how to encountering it and i got my first biotoxin because that

Ez kill. All you have do is craft a bow and at least 11-15 of them depending on the group. And shove a few arrows into their heads and that’s it. Again, ez kill

I dunno what all the hate is about, for a low level mobile player on a difficulty that keeps most creatures below level 40, these things really aren't bad. Sure, it'd be suicide to go in the water with them beside u, but they are the only viable source of biotoxin for me, that's gotta count for something. They're super easy to avoid once u get to know them and most times they don't even spawn near the necessary crossings at shallows, only in deep sea where most tames are entirely capable of out swimming them. Heck, I took on four cnidarias with the weakest of them being level 19 with a ramshackle pike and they barely did 200 damage to me. Just don't go at them with anything less than a basilo and they're fine. Those eels are the real worrisome ones, but cnidaria just aren't really a concern for me.

These guys bio toxin is easy to get and is very effective for keeping dinosaurs asleep

Tip for beginners: dont get close to this creature. This is shock you and stop to moving for you. You can kill it with pike. Be careful.

I feel like you should be able to tame these guys and ride them. They could have a move that paralyzes your enemies. Up if the devs should add

Me after taming diplo: FINALLY!

Diplo:sup

Me: I’m going to cross the river let’s go.

Cnida: hmm that Diplo looks good.

Diplo gets kill

Me:NOOOO!

Ps:it took me a day (technical two half of day) to tame Diplo but, it took like 15seconds for cnida(s) to kill it plz up if this happened to you but similar R.I.P no name😔

If you have a paracer you can traverse the shallower waters and the jellies won’t seek you out. ( At least on mobile this seems to be the case.)

Me: go in ocean

Them: attak

Me: no
